Display notification if any new item has been added

I have field which displays number of loans present in a deal. I want to show an asterisk mark(as shown in the below image for #25) for that field if any new loan has been added for that deal. Is there a way to show the asterisk mark? The sole purpose of this implementation is to notify the end user that there has been some update since his last log in. Kindly, suggest if you have any idea. I have attached a screenshot for reference.

If you could easily compare the old and new value you could use the microflow timer widget to make the comparison every x seconds, and if there is a change, you could display the asterix as a separate text value with conditional visibility.
